CUTTING-OUT PRESS.

SPECIFICATION forming'part of Letters Patent 1V0. 732,101, dated June30, 1903. Application filed November 12, 1901. Serial No. 81,989. (Nomodel.)

ing to be afull, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to c utting-outpresses,

character of press in which a vertically-re.

ciprocating head or buffer descends upon a knife previously placed uponleather, paper, cloth, or other material to be cut laid on the table ofthe press and forces it (the knife) through the material, therebyproducing a blank of the required'shape and size-such, for example, as asole, top piece, lift, stiffener, or other part of a boot or shoe or anenvelop, label, or other article. As is well understood, in connectionwith presses of this type the knife is first arranged by the operator inthe proper position on the material to be out, and then the two (knifeand material) are moved by the operator under the descending head of thepress, which presses upon the knife with sufficient force to cause it tocut out the blank, and this operation is repeated. In this connection itwill be noticed that the operator is continuously handling the knife andmaterial to adjust the former in proper position on the latter beforeplacing the same under the press, and a certain amount of unnecessarytime is involved in this operation which it is the object of the presentinvention to avoid for the purpose of increasing the output of thepress-'5. e., the number of articles cut thereby in a given time.

According to this invention there is no necessity whatever for thepressman to ban-- dle the knife, as the knife is carriediin the head orbuffer of the press and can be lowered This invention thereforecomprises as its essential feature a knife detachably supported in thehead or buffer of the machine and means for lowering it onto thematerial independent of the mechanism by which the head of the press islowered to perform the cutting operation.

The invention will be understood from the following further descriptionin reference to the accompanying drawings, in which- Figure 1 is a sideelevation of sufficient of a press of the type referred to to illustratemy invention which is applied thereto, the knife being shown in itsraised position. Fig. 2 is a front elevation of the press, showing theknife lowered onto the material preparatory to being forced through thelatter. Fig. 3 is a similar view showing the buffer as having descendedontothe knife and forceditthrough the material to out out the blank.Fig. 4 is a plan of a knife having a projecting flange all around to fitinto the groove in the knifecarrier bars. Fig. 5 is a similar viewshowing the knife provided with projections at each end instead of acontinuous flange. Fig. (5 is a vertical section on the line X X of Fig.4. Fig. 7 is a similar view on the line Y Y of Fig. 5.

1 represents the standard or framing of the press, in the upper part ofwhich is a driven shaft 2, carrying on its end an eccentric 3, whichraises and lowers a rod 4, the lower end of which is located within acavity in the upper end of a plunger 5, carrying on its end a head orbufier 6, which descends upon a knife 7 and forces it through leather orother material 8 to cut out a blank or shape therefrom. While the rod 4moves up and down in the deep cavity 9, as in Fig. 2, the plunger 5 andbuffer 6 on the end thereof are not depressed, but remain quiescent; butwhen the rod a is moved laterallyinto the position indicated in Fig.3the end of the rod 4: 'descends upon the ledge 10 and lowers the plunger5 and buffer 6, the latter onto the 'knife 7 to force'it through. thematerial 8.

The rod 4 is moved into the position shown in Fig. 3 to depress theplunger at the required time by means of an arm 11 on the end of arocking shaft 12, carried in bearings 13, Fig. 1, on the side of theframing and actuated through the medium of a short arm 14.- and rod 15connected thereto, which rod is pedal.

rod is lowered by means of another rod 16,

lowered for that purpose by depressing a foot- In the present instance,however, the

leading down to a foot-pedal. (Not shown in the drawings.) When thelast-named rod 16 is lowered, a fixed guide-block 17 thereon, andthrough which the rod 15 also passes, bears upon a fixed collar 18 onthe rod 15 and depresses the latter to rock the shaft 12 and move thearm 11 against the eccentric-rod 4, as hereinbefore described. When theoperators foot is removed from the pedal, the latter is raised by aspring, as is common to most pedal-machines, thereby withdrawing the arm11, which by means of a spring 19, connected thereto, also withdraws theeccentric-rod4intoitsinoperativeposition. (Shown in Fig. 2.)

So far the press is of well-known construction.

For the purposes of this invention the knife is provided either with aprojecting flange 20, Figs. 1, 4, and 6, or projections 21, Figs. 5 and7, secured thereto by screws 22. The said flange or projections is orare adapted to be slid into two grooved carrier plates or bars 23 24,located under the bufier 6 and one on each side thereof. Eachcarrier-plate 23 24 is supported by two short rods 25 26, projectingupwardly therefrom and terminating in a'hook 27, Fig. 1, connecting itto a spring 28,

the other end of which is attached to the hooked end of an arm 29,projecting from a collar 30, fixed to the tubular sleeve or boss 31,forming an integral part of the framing of the press and in which theplunger 5 is located. The said springs keep the carrierplates normallydrawn close up against and in contact with the under surface of thebuffer6-t'. e., in their raised positions. Each carrier-plate has alsotwo other rods 32 33 rising upwardly therefrom, connected at their upperends by a bridge or cross-bar 34, fastened thereon by nuts 35. Bearingon each of the two cross-bars is the curved end of a lever 36, fulcrumedat 37 to the boss 38, the object of which lever is to depress the saidcross bar 34, and thereby also lower the knife-carriers 23 24 until theknife rests on the material, as shown in Fig. 2, preparatory to thedescent of the buffer 6 to complete the cutting operation. Each lever 36receives its motion to lower the knife from a connectingrod 39 and lever40, the two levers, one each side of the framing, being carried on arocking shaft 41, passing through the framing, and to one end of thesaid shaft there is attached an arm 42, connected also to the rod 16,which leads down to afoot-pedal from which the said rod is actuated, ashereinbefore described. A spring 43, attached at 44 to the framing andalso to the lever 40, restores the lever 36 to its normal and originalposition, as shown in Fig. 1, after it has lowered the knife 7 onto thematerial, and the springs 28 raise the knifecarriers 23 24 and the knife7 after the cutting operation. Plates 45 46, depending from each side ofthe buffer 6, Figs. 2 and 3, to the edge of which they are fastened byscrews 47, form guides for the knife-carriers in their upand-downmovements. A lever 48, fulcrumed at 49 to the end of the groovedcarriers 23 24, may be placed in front of the knife-plate, as indicatedon the left-hand side of Fig. 1, to keep the knife from sliding out ofthe grooves therein and moved into the position shown on the right handside of the same figure when it is desired to remove the knife for thepurpose of taking out the blanks'therein. The depth of the knife isconsiderably i11- creased, so as to reduce the frequency of its removalfrom its carriers for taking out the blanks therefrom. A stop-pin 5Olimits the movement of the lever in each direction. The springs 51 52,connected at one end to the bufier 6 and at the other end to the boss31, raise the buffer 6 after it has been lowered for the cuttingoperation and maintain it normally at its highest point.

The action of the press is as follows: The operator places his foot uponthe foot-pedal, thereby lowering the rod 16, which, acting upon thelovers 40, connecting-rods 39, and levers 36, depresses the cross-bars34, and thereby lowers the knife-carriers 23 24 and the knife 7 untilthe latter rests upon the material 8 to be out. By the time the knifehas reached the material the guide-block 17 has come into contact withthe fixed collar 18, which is pressed downward thereby, thus loweringthe rod 15, rocking the shaft 12, which causes the arm 11 to move theeccentric-rod 4 onto the ledge 10 of the plunger 5, thereby suddenlydescending the latter and the buffer 6, which bufier, falling on theknife 7, forces the latter through the material and cuts out the blank.Upon the operator removing his foot from the pedal the movement of theparts is reversed, resulting in the knife 7, knife-carriers 23 24, andplunger 5 being returned to their raised positions in Fig. 1.

By means of this invention the operator has both his hands at liberty,(instead of having to handle the knife,) and by placing his foot uponthe pedal he can lower the knife for the purpose of adjusting thematerial in position underneath it preparatory to the descent of thebuffer to force the knife through the material and cut out the blank.

The invention is applicable to other types of cutting-presses withdescending or vertically-reciprocating heads or buffers than the onehereinbefore described, and illustrated in the accompanying drawings.
